Definitions
- the invention relates to thermoplastic polycarbonate compositions containing Interfe rence and / or pearlescent pigment from the group of metal oxide-coated mica, and moldings of these compositions.
- Effect pigments are platelet-shaped and cause a directed reflection and / or interference.
- effect pigments metallic effect pigments, interference pigments and pearlescent pigments, with the boundaries between the latter in particular being able to be fluid and therefore also collectively referred to as "special effect pigments”.
- Pearlescent pigments comprise transparent platelets of high refractive index. Multiple reflection creates a pearl-like effect.
- the coloring of interference pigments, which may be both transparent and opaque, is based primarily on interference.
- the pearlescent and / or interference pigments also include, in particular, metal oxide-coated mica pigments which find application in various fields, for example for housings of numerous devices in the household or consumer electronics or as a design element in the architectural sector.
- Pearlescent effects and / or interference pigments of this type are available, inter alia, from BASF SE under the names "Magnapearl®” or “Mearlin®” or from Merck SE under the names "Iriodin®” or "Candurin®”.
- DE 20 19 325 A1 discloses pigmented aromatic polycarbonates having a content of about 5 to about 100 percent by weight of epoxide group-containing copolymers, based on the pigment content.
- WO 2016/096696 A1 describes a thermoplastic molding composition
- a thermoplastic molding composition comprising g) 5 to 99.9% by weight of at least one thermoplastic polymer as component A; h) 0.05 to 10 wt .-% of at least one coated with a metal oxide mica as component B; i) from 0.05 to 50% by weight of at least one flame retardant other than component B as component C; j) 0 to 35% by weight of at least one functional polymer other than component A as component D; k) 0 to 60 wt .-% glass fibers as component E and 1) 0 to 10 wt .-% of further auxiliaries as component F, wherein the total amount of the components A to E 100 wt .-% results.
- EP 0 158 931 A1 relates to thermoplastic molding compositions comprising: A) from 10 to 80 parts by weight of an aromatic, thermoplastic polycarbonate, B) from 10 to 60 parts by weight of a graft polymer of ethylenically unsaturated monomers onto rubbers having a rubber content of from 5 to 80 Wt .-%, based on the weight of component B) and C) 10 to 60 parts by wt.
- a thermoplastic, resinous, high molecular weight, rubber-free copolymer wherein the sum of the weight parts A + B + C is 100, and optionally D) 1 to 20 parts by weight, based in each case on the sum of parts by wt.
- a + B + C + D which in turn is 100, of an at least partially crosslinked butadiene-acrylonitrile copolymer rubber, the acrylonitrile to butadiene in a weight ratio from 15 to 85 to 35 to 65 in copolymerized form, and which has a particle size of 0.05 pm to 0.3 mip.
- Component C contains from 0.05 to 5% by weight, based on the weight of component C, of an ethylenically unsaturated epoxide compound.
- EP 0 718 354 A2 discloses thermoplastic, aromatic polycarbonates with
- Phosphine stabilizers examples include tris (4-diphenyl) phosphine or tris (a-naphthyl) phosphine.
- pearlescent pigments or interference pigments from the group of metal oxide-coated mica When used in polycarbonate compositions, pearlescent pigments or interference pigments from the group of metal oxide-coated mica usually lead to a significant degradation of the polycarbonate, resulting in a reduction of the molecular weight and a concomitant reduction in viscosity and thus increase the melt volume flow rate MVR and deterioration the mechanical properties shows.
- the degradation processes also lead to a discoloration of the material.
- the degradation processes are taken into account by using polycarbonate of higher molecular weight than is needed for the actual application.
- the target molecular weight is then achieved by the compounding and injection molding or extrusion processes at elevated temperature.
- other parameters in the compounding process such as the control of the energy input or the arrangement of the dosing for the effect pigment, a significant impact on the ultimately resulting Molekularge weight of the polycarbonate.
- targeted control of the molecular weight is problematical.
- thermostabilization of polycarbonate usually suitable organic phosphorus compounds such as aromatic phosphines, aromatic phosphites and organic antioxidants, in particular sterically hindered phenols, are usually added.
- organic phosphorus compounds such as aromatic phosphines, aromatic phosphites and organic antioxidants, in particular sterically hindered phenols.
- phosphites in combination with sterically hindered phenols is frequently described, for example in EP 0 426 499 A1.
- the stabilization only by phosphites is not sufficient in the case of the effect pigments described.
- the object was thus to provide polycarbonate compositions containing pearlescent and / or interference pigments from the group of metal oxide-coated mica, which exhibit the least possible degradation of the polycarbonate during compounding, so that the disadvantages described above are avoided as far as possible.
- the object is achieved by adding epoxy group-containing copolymer or terpolymer of styrene and acrylic acid and / or methacrylic acid in combination with a phosphite thermostabilizer to form a polycarbonate composition containing pearlescent and / or interference pigment (s) from the group of US Pat Metal oxide-coated mica, is dissolved.
- Thermoplastic compositions according to the invention are therefore those containing
